SN74AUC1G08YEAR

Overview

The SN74AUC1G08 is a single 2-input positive-AND gate from the Texas Instruments AUC logic family. It operates within a supply voltage range of 0.8 V to 2.7 V, with specific optimization for 1.65-V to 1.95-V applications. The device supports mixed-mode signal operation through 3.6-V I/O tolerance while maintaining sub-1-V operability. Key electrical characteristics include a maximum propagation delay of 2.4 ns at 1.8 V and a maximum quiescent current of 10 µA. Output drive capability reaches ±8 mA at 1.8 V.

Feature Summary

• Supports partial-power-down mode via Ioff circuitry that disables outputs to prevent back-drive current flow.
• Provides robust electrostatic discharge protection exceeding JESD 22 standards across multiple test models.
• Features latch-up performance that exceeds 100 mA per JESD 78 Class II requirements.
• Enables mixed-mode signal operation by supporting 3.6-V I/O tolerance alongside low-voltage core operation.

Applications

• Portable audio devices such as MP3 players and recorders
• Solid-state drives for client and enterprise storage systems
• High-definition television and video analytics servers
• Wireless peripherals including headsets, keyboards, and mice

Procurement Notes

Verify the specific package type required for your design, as the SN74AUC1G08 is available in SOT-23, SC70, SOT-5X3, and DSBGA configurations. Confirm that the selected variant meets your thermal resistance and board space constraints. Ensure input pins are tied to valid logic levels during operation to maintain stability. Check the latest orderable addendum for current moisture sensitivity levels and reflow temperature profiles before finalizing procurement.

Selection Notes

Select this component when designing low-voltage digital circuits requiring a compact AND gate solution. It is suitable for battery-powered portable electronics due to its low power consumption and wide operating voltage range. Consider the specific package dimensions if space is limited, as options like NanoFree provide minimal footprint. Ensure the application environment stays within the specified -40°C to +85°C temperature range for optimal performance.

Part Context

This device belongs to the SN74AUC1G series, which focuses on ultra-low voltage and high-speed performance in small packages. The AUC family is designed to replace older logic families in modern low-power applications. The SN74AUC1G08 specifically provides a single 2-input AND function, making it a fundamental building block for complex digital logic designs in consumer and industrial electronics.

Replacement Considerations

Direct replacements include other variants within the SN74AUC1G series or compatible parts from other manufacturers offering similar 2-input AND functionality in 5-pin packages. Verify pinout compatibility and electrical specifications such as propagation delay and output drive current. Ensure the substitute part supports the same supply voltage range and I/O tolerance requirements for seamless integration.
